Anyone know much about tuning cars?

[jnevin]

I'm going to be getting a new car soon and I was thinking of messing with the one I have to make it faster. It's a '99 Impreza RS. I want to keep it street legal, but I don't know what I can do to it that won't wreck it in a year.

I'm thinking of intake, headers, exhaust, cams, pulleys, suspension, and brakes. It's normally aspirated and I don't want a turbo.

Anyone done anything like this, and how did it turn out?

I heard a type-s sticker adds 20hp.

seriously though, i put this body kit and it improved the shit of my accords aerodynamics.

Honda OEM aero kits

Lol. The spoiler added like... 30.

Really 'do. How bad is this for the engine? I'll have it rebuilt and all, but I'm thinking I can get up to 90 hp from all of this.

Dood, I want it to be fast, but not too fast. I really hope that isn't really someone's car.

It's probably Valentino's synthol powered ride.

get a E30 m3 to tune )ole school m3 and so fast, so light so many tuner parts out there)

get a skyline GTR to tune ( u have the money)

you have the right idea,thats basically all you can do to it without adding turbo or a supercharger

 

[JarheadChiro]

I have a cold air intake, K&N filter, larger diameter exhaust pipes, high flow cat converter, performance headers and mufflers on my Acura.

Added about 30-35 HP.

Here are some mods i did to my GTI (Turbo) if your looking for ideas.

2.5" Miltek Turbo Back Exhaust
R32 Front Bumper
18 inch wheels
Neuspeed 28mm Rear Sway
APR Chip 93 Program
Cold Air Intake
Forge 007 Diverter Valve
ECS Race N75 Valve
Diesel Geel Short Shifter (reduces the throw by 50%)
Greddy Turbo Timer

and a bunch of other cosmetic shit.

If you're gonna have it rebuilt then why not go with a turbo charger? All forged components, high flowing heads, 8.5:1 compression, little overlap cam. While the engine is pulled that'd be the perfect time to do the turbo-charger plumming. Or do all that, increase the compression ratio with some high compression pistons then run Nitrous (not 'Nahs', dont say it like that, ever).

I'd just buy a new M3 if that was the case. I want to do this because the car is paid for and I can do it for a few thou.

I may have a kid on the way, :stress: so just about everything I make is going toward that. I was thinking I could buy a WRX engine and swap it.

Buy a 2003 or 2004 cobra, and port the supercharger upper and lower pulley, and all of a sudden you have 500+ RWHP, for around a 1000.00

that's what I'm talking about.....muscle. I was going to get a 04 Mustang GT, but everyone around here has 'em, so it's kind of boring. I'm looking at a 00 Trans Am right now, but I've got to drive 2 hrs to look at it. but 305 hp stock, only mods are exhaust...Flowmasters. can't wait to go see it.

Nieghbor had a mustang 5.0 (f'n 307 crap). He dumped the exhaust and put pipes on, thus losing the backpressure of the catalitic and standard pipes. He then purchased a tuning PC, hand held device, which can change the timing, air:fuel ratio and other tuning components. Baring full modification of the engine, this could bring up performance simply by changing the program to be a hotter set. I think he also modified a chip from standard to race, but not sure. Of course the pipes he added were illegal and if caught was a big fine. But how many cops look under your car?

You ingnoramous's....I hate imports and I hate it when people think that "adjusting" or getting a "chip a.k.a usually a cheap resistor" gives them like an extra 60 horse. You dont want to reduce backpressure to much either...Stupid people...The whole K&N air filter adding 15 horse is a bunch of crap also...yeah its a good air filter but you dont get 15 horse by doint that...Lmao.

first off a Mustang isn't an import. If some body wants to put a chip in their car for increases HP, so be it, that's their choice.
And yes, reducing back pressure is a good thing. Increasing exhaust output size, headers, reduces back pressure, which is like increasing overlap time. Overlap time is the time when your exhaust valve is closing and your intake valve is opening up, letting air/fuel into the cylinder. At higher rpm's it is to your advantage to have increased over lap because things are moving so much quicker, the gasses have little time to escape the cylinder which robs you of power. So by reducing back pressure, you increases high end HP, but lose a little low end torque. But yes, too little back pressure is bad as well.
THe best way to go for best performance would be to get a better cam to increase overlap and get the right exhaust to go w/ it.

Thats cool bro, I here you about driving to look at it, I got my car shipped from Texas. Is it a WS6?

no it's not the ws6 unfortunately. I wonder how much better they drive compared to the reg. T/A. Apparently it has a better shocks, bushings, sway bar along w/ the different hood. I can buy the hood online for like $700, which I plan on doing and probably buy the ws6 sway bar. the guy wants 14500 for it, but i'm going to offer him 13000. I think that's reasonable. It only has 55,500 miles, t-tops of course. z-rated tires.

As stated, the Stang is made in um, CANADA? but a US car. The chip and tuning are a part of the system which is computer controlled. no more timing lights, points and other BS.

The 5.0 (302) has multiple chip sets. Standard underpowered stang, Street HOT stang and the race chip. By inserting the race chip, you can achieve whatever the max hp of the engine is. Of course you need to have the access panel to do so.

As for backpressure, you are correct. But, by using the chips properly, and with the full dual exhaust and pipes etc., you can correct the tuning, again by using the computer, achieving max HP on a basically street sled.

My thoughts on the 5.0? My 327 kicked it's ass when it was the BOSS 302, and that was in 68. I doubt if it is any better today. But, if you have the right machine and tools, you can boost it up for a faster street legal machine.

(edit: oops, was a Boss 302, and the 5.0 is not 307 (cheby) but a 302)

Motor swapping the rs is not just a plug and play affair. You're looking at all new wiring harnesses, motor, trans, and all the little stuff. Then you will need better brakes. . . it never stops

You need to set a goal.

What will the car be used for

How often will you drive this car

How much are you willing to spend

There are several options out there, and I'm sure the ef population will have an opinion on them.

Answer those few questions and I'll let you know what I think would fit the bill.
